About Gamersyde
Gamersyde is a commercial multiplatform web portal based in Europe, with hundreds of thousands of visitors each month from all over the world. We cover both handheld and video games platforms and the site has grown into one of the biggest gaming sites in the continent. We are able to offer fast news delivery and HD content from the upcoming games, and one of the greatest and friendliest gaming communities in the world. The HD content we provide always respects the original resolution and framerate of the games we capture, making Gamersyde the one and only place to get 1080p/4K/60fps videos with high bitrate. At a time when Youtube's subpar video compression has become the norm for most people on the Internet, we refuse to give up quality without a fight. We now also produce HDR videos, which can only be enjoyed by those who own compatible televisions. The content we produce is obviously not free of use should you want to upload our videos on your own website or YouTube channel.

Since 7016 DaysInstead of selling a external HDDVD they could have it intergrated and keep the price. I don't give a sh*t about pricedrops. It's the gaming that's important. That's why PS3 is going to defeat XBOX 360 next year and the year after until another next-gen consoles gets released. Then probably discs will have 300 GB space but Microsoft will stick with intergrated HDDVD. Idiots !! =/

Since 7016 DaysAn example of a procedural texture:

Since 6987 DaysAs for procedural textures, I think quality is the biggest issue. But if you could get quality textures from procedural methods, there is no reason not to create them while loading or caching data. Imagine this scenario:
You are starting a new level in PGR5. You have 100MB of audio, 100MB of geometry, and 200MB of textures to cache before the user can begin racing. Lets assume magically 50% (100MB) of those textures could be procedurally created on the GPU.
So lets say it takes 40 seconds to stream 400MB to system memory, so what if you could write 300MB in 30 seconds and at the same time create 100MB of the textures procedurally?
They are stored in memory like any other texture, but instead of coming from the disk they were created in memory by a procedural generation application.
We aren't quite there yet... but we are getting closer. Much closer. So much so I think the next wave of consoles will rely on such techniques in a significant manner because of the benefits in modification, reduced artist load, reduced memory transfer (imagine 4GB of system memory and a BDR transfering to it... no, just no!) and such.
We will see though, although the field is very interesting and fast moving. MS talked it up a lot at GDC 2005 and as time goes on it will become more popular in content creation -- because applications are cheap, artists are not -- for things like cities, forests, etc.
The fans have spoken. Concerning the graphics of the Halo 3 Beta: "There's so many little effects and things going on that make this game pretty much 2nd only to Gears at the moment."
Since 7718 DaysSee the example there; it's a combination of layers of alphas and patterns. It still takes an artist a lot of work to create it (and some programming apparently when it comes to games). I use procedurals a lot in my work mainly because UV's are a bitch. ;)
From what I'm reading the main consideration actually is storage limitations, and the randomness procedurals can create.

Since 7718 DaysMath is hard for artists? Tools for creating procedural texture will *become* available? You really have no idea what you are talking about, I'm sorry, because procedurally generated textures have been around since the first 3d app on PC's.

Using these tools does not require a very complete understanding of how procedurally generated textures are actually being generated.
Since 7718 DaysI have never seen a texture generated by code like that. But you can install Modo and layer textures and play with layers and blending options 'til the cows come home if you like, and you will never need to enter a lick of code.

I am not arguing for the sake of arguing, I happen to be a 3d artist. And I do not know what acert's field is, but I am willing to bet that I was required to take more math and physics classes than he has taken.

Generating a fractal, which is one of the most basic examples of procedural generation is ALL math, and it requires a pretty good handle on math and programming to make that happen -- that's not too far off from what we're talking about in the real time implementation of these concepts in a videogame.
Since 7718 Days......
Forget it.

I'm not arguing that artists don't use procedural tools.. just that procedural algorithms can indeed by implemented in ways that save time for the artists, which saves man hours, and in the end, takes away from the amount of hand painted textures they might have to use.
There's a game that's in the kilobyte range.. you should check it out. You can bet that the person who implemented those procedural algorithms has a pretty wicked handle on math, and isn't necessarily an artist.
Since 6987 DaysSome nice videos that only use procedural textures. Some pretty nice textures... this is the same company who did the tech the Roboblitz folks used.
Most of the demos use less than 512KB in size for the app and textures and generate 100s of MBs of textures... and more importantly the materials, as they are procedurally created, and be altered as such. So you scuff a wall, for example, and it can get a scratch as per determined by the material characteristics of the texture.
The bathroom scene is very impressive because you can see how the bathroom ages and how plaster cracking reveals wood behind the wall -- all procedurally created.

Since 6987 DaysAnd related to procedural textures is MS's patent on procedural synthesis which Ars broke down many moons ago: http://arstechnica.com/articles/paedia/cpu/xbox360...
The idea of using basic stock material and using applications to generate the content by user defined criteria (e.g. I want 100-150 pine trees per acre of various heights from seedlings to 200ft with the averge being 125ft and the median being 100ft, with average-to-thick density) is definately gaining steam because it allows artists to create masses of content quickly and for them to fine tune later if they so choose. This is exactly what Speedtree does. http://www.speedtree.com/
Right now most procedural synthesis is done at creation time, but eventually it will be done in some circumstances at loadtime and eventually even at runtime (many procedural texture applications are in the range of 40 ops).
The fact is games are using procedural technologies now and have been and they will only become more common as games need more art assets and hence artists, which are expensive, and game size increases but storage medium transfer rates remain low.

Since 6908 Days20GB of textures or something like that while only taking up 2GB of space was it?

Don't ask any questions just shut up and buy Halo : Ghosts of the Onyx one of the greatest books ever.
Since 6888 DaysArtists still have to paint and create their own textures. More importantly procedural algorithms wouldn't require that artists suddenly becoming coding masters. The artist can continue to create whatever he wants.

Hopefully it doesn't take away too many valuable resources from other aspects of the game. I suppose it shouldn't especially since the 360 was designed with this in mind?

Since 6711 DaysYou just can't get full NEXT-GEN games with DVD-9.
Blue-Ray and HDDVD were available in the end of 2005. PS3 announced years ago that the PS3 will have Blue-Ray.
The external HDDVD-player only gives 1080p when watching movies but it can't be used too develop HDDVD-games. If they do that then all 360-owners will get mad to pay more money to play the best games. 199$ is expensive.
Huge d*ckmove by MS and the second hugest mistake after the hardwareproblems !!
Xbox 360
Halo 3 - Call of Duty 4 - Bioshock - Turok
Since 6884 DaysIn terms of business, not including HD-DVD is the smart move. Of course for us we want everything and will probably have paid $500 odd for a HD-DVD 360 anyway.
As for procedural texturing, the load times in PG3 were bad enough (though they were rushing for launch so I'll let them off) but does anyone have any idea how long we'll be waiting for an entire city to load up with procedural textures? It'll be like going back to the C64 days on current hardware!
It's a nice tech but not applicable in all situations.
Since 7039 Days
Since 6884 DaysTo be fair to PGR4, 10 cities the size of the first one makes for a pretty big game so it's not like we're being undersold. When we get to the point of needing the space just to get a decent length game out we'll have more things to worry about.
Still, such things might appear as DLC as 500MB for this isn't a big ask. If it's only a matter of rebaking the textures there's no reason why it can't be done for those willing to make the HD space.
